Instant Kill

Sector type 8, Instant Kill, is a sector type which kills the player instantly upon touching any part of the sector. Unlike a death pit, the player is not just killed when touching the floor, but also in midair. In NiGHTS levels, these sectors do not cause damage in 3D mode due to all damage being disabled; in 2D mode, they cause normal NiGHTS damage.

The instant kill effect was used in Techno Hill Zone Act 3 prior to v2.1, so that the player would die if they jumped too far away from the train. It is also commonly used as "acid damage" in many custom levels. In this context, it is used on a translucent water FOF with a #999999Dcolormap that fades to #00FF00Z, GOOP01 flats and AFALL1 textures.
